Collagen extraction of tilapia scales (oreochromis niloticus) for development of nutricamistic and dermatological product

The development of products obtained from tilapia scales, besides being innovative for the pharmaceutical industry, can result in numerous benefits for the environment, since they are low cost and are generally discarded in dumps and landfills, and that can generate environmental impacts. The present work aimed to develop a dermatological and nutricosmetic product from tilapia scales, as well as bibliographic survey of its benefits for human health. This research has an experimental and investigative character, which includes the extraction of gelatin from tilapia scales, which have been undergone to several acid and basic baths, heating and drying. Subsequently, two products were developed, one for dermatological and the other nutricosmetic use, called with the fancy name of revitalizaderm and gummy BEV, respectively. After obtaining the products, pharmacotechnical and microbiological tests were performed. The microorganisms investigated were Escherichia coli,Salmonellaand Staphylococcus aureus, presenting negative results for the culture. The physical-chemical tests performed in the samples were: organoleptic characteristics, pH, spalmability and relative density. It should be noted that the developed products were not used in vivo, so their possibility of effectiveness is based on literary data. Then, further studies will be carried out to evaluate their activity.
